Welcome to the forums

What specifically is the problem that you’re having with your code?

after i enter the number of the 3 currencies it displays dollars = 0 in the terminal dont know why

I dont worry I just found the problem isteand of using 0, i used 0. beacause in my country we use , for decimals and this is an english based language i forgot but thanks for volunteering to help me

this is the correct version https://gist.github.com/972ba608d965fb0735f0db591340abfc

Yes I was just about to say. Remember that it’s not like Latin America with the decimal points.

right thank you very much although im actually from Spain.

Ah I didn’t know Europe also uses this, sorry. I’m from Latin America.

What would you like to do or learn?

Could someone explain the following for me?

question: An organizer of a 64-person meeting wants to start by having every person individually greet each other person for 30 seconds. Indicate whether the proposed solution achieves the goal without using excessive time. Before answering, think of a possible solution approach for this seemingly simple problem.

Answer: With two lines, 32 * 30 seconds is used. Then the lines split, yielding 4 lines (16 and 16, and another 16 and 16). 16 * 30 seconds is used. Then 8 lines (8 and 8, 8 and 8, 8 and 8, 8 and 8), so 8 * 30 sec. And so on. Total time is about (32 + 16 + 8 + 4 + 2 + 1) * 30 sec, or 63 * 30 sec. This solution is an example of a “recursive” solution (discussed elsewhere).
